There are only r red counters and g green counters in a bag.
A counter is taken at random from the bag.
The probability that the counter is green is 4/9
The counter is put back in the bag.
4 more red counters and 2 more green
counters are put in the bag.
A counter is taken from the bag.
The probability that the counter is green is 10/23
Find the number of red counters and the number
of green counters that were in the bag originally.
Your final line must say,
... red and ... green counters.
